v4.14.0

Features

• Three new features related to Generative AI have been added: Form type, Suggested replies and Feedback.
  • Form type: A form type message is a message that contains a form. A form is a set of questions that a user can answer to collect data from users.
    1. How to determine if a message is a form type message:

       val BaseMessage.isFormTypeMessage: Boolean
           get() = this.forms.isNotEmpty()

    2. How to save the answer in the SDK when the user enters input:

       editText.addTextChangedListener(
           object : TextWatcher {
               ...
               override fun onTextChanged(s: CharSequence, start: Int, before: Int, count: Int) {
                   formField.temporaryAnswer = Answer(formField.key, s.toString())
               }
           }
       )

    3. Submits a form

       // submits form
       message.submitForm(form) { e ->
           if (e != null) {
               // handle error
           }
       }
       
       // The submitted form is updated through a message update event.
       SendbirdChat.addChannelHandler(
           "IDENTIFIER",
           object : GroupChannelHandler() {
           ...
               override fun onMessageUpdated(channel: BaseChannel, message: BaseMessage) {
                   message.forms.find { it.formKey == "TARGET_FORM_KEY" }?.isSubmitted // should be true
                   // update message UI to submitted form
               }
           }
       )

  • Suggested replies: Suggested reply is a set of items that a user can click quickly to send a message. Suggested replies is contained in a last message.

    SendbirdChat.addChannelHandler(
        "IDENTIFIER",
        object : GroupChannelHandler() {
            ...
            override fun onChannelChanged(channel: BaseChannel) {
                if (channel is GroupChannel) {
                    val suggestedReplies = channel.lastMessage?.suggestedReplies
                    if (!suggestedReplies.isNullOrEmpty()) {
                        // draw suggested replies for the channel's last message
                    }
                }
            }
        }
    )

  • Feedback: Feedback is a feature that allows users to provide their satisfaction or dissatisfaction with the bot's responses.
    1. How to draw feedback UI

       val feedback = message.myFeedback
       when (message.myFeedbackStatus) {
           FeedbackStatus.NOT_APPLICABLE -> {
               // this message is not applicable for feedback
               // Make thumbs-up/down UI invisible or disable here
               // `feedback` should be null
           }
       
           FeedbackStatus.NO_FEEDBACK -> {
               // The feedback is not submitted yet but user can submit feedback
               // Make thumbs-up/down UI visible or enable without being selected
               // `feedback` should be null
           }
           FeedbackStatus.SUBMITTED -> {
               // The feedback is submitted
               // Make thumbs-up/down UI visible or enable as selected
               // `feedback` should not be null
           }
       }

    2. How to submit / update / delete feedback

       // submit feedback
       message.submitFeedback(FeedbackRating.Good) { feedback, e ->
           when {
               feedback != null -> {
                   // update feedback UI
               }
               e != null -> {
                   // handle error
               }
           }
       }
       
       // update feedback
       message.updateFeedback(FeedbackRating.Good, "Very good response") { feedback, e ->
           when {
               feedback != null -> {
                   // update feedback UI
               }
               e != null -> {
                   // handle error
               }
           }
       }
       
       // delete feedback
       message.deleteFeedback { e ->
           // handle error
       }
